name aubrie

1. on the nba website you can find information about all the current players, such as ppg (points per game), height, weight, team, and position. which of these variables are categorical and which are quantitative?
2. which of the following graphs show relative frequencies? select all that apply.

□ frequency bar chart
● relative frequency bar chart
● segmented bar chart
● pie chart

1. the bar chart shows the number of tornadoes that touched down in the united states in a recent year for each month. are the data displayed in the bar chart categorical or quantitative? explain.
2. you have been asked to research 5 colleges/universities of interest to you. list 3 categorical variables and 3 quantitative variables that you would like to obtain information about for each of your selected colleges/universities.

Explanation:

Step1: Identify variable types for NBA data

Quantitative variables are numerical. Height, weight, PPG are numerical, so they are quantitative. Team and position are non - numerical labels, so they are categorical.

Step2: Determine graphs showing relative frequencies

A relative frequency bar chart shows relative frequencies directly. A segmented bar chart and a pie chart can also represent relative frequencies as they show proportions of a whole. A frequency bar chart shows absolute frequencies, not relative ones.

Step3: Analyze bar chart data type

The bar chart shows the number of tornadoes (a numerical value) for each month. Since the data is numerical, it is quantitative.

Step4: Suggest variables for college research

Categorical variables could be: type of college (public/private), location region (east/west/mid - west/south), academic focus (liberal arts/STEM/business). Quantitative variables could be: tuition cost, average SAT score of incoming freshmen, number of students.

Answer:

1. Quantitative: height, weight, PPG; Categorical: team, position
2. Relative frequency bar chart, Segmented bar chart, Pie chart
3. Quantitative. The data represents the number of tornadoes, which is a numerical value.
4. Categorical variables: type of college, location region, academic focus; Quantitative variables: tuition cost, average SAT score, number of students
